Return to Requirements

The Part 5 handoff SHALL identify implementation traceability relationships.

Part 4, Section 21.15: Part 5 Handoff Requirements.

Part 5 must preserve the architectural justification for the implementation artifacts it deploys, tests, observes, operates, and evidences.

Including implementation traceability relationships in the handoff allows Part 5 evidence and operational records to remain connected to the FX logical and implementation sources defined by Parts 3 and 4.

This requirement applies to:

• Node implementation traceability;
• Topic implementation traceability;
• IDL and generated type traceability;
• Runtime Plane implementation traceability;
• script and repository traceability; and
• Developer Handbook traceability.

Verification SHALL confirm that the Part 5 handoff identifies applicable implementation traceability relationships.

Verification activities should include review checks confirming that:

• forward traceability remains available;
• backward traceability remains available;
• implementation artifacts retain their logical or implementation sources; and
• Part 5 can preserve these relationships in later deployment and evidence records.

This requirement carries the Part 4 Implementation Traceability Model into Part 5.
